- the automatic cleaning apparatus 2000 controls the body to rotate by a certain angle, for example, 15 degrees counterclockwise as shown in FIG. 22 , if the carpet is detected before the automatic cleaning apparatus 2000 sweeps along the edge of the carpet.
- the automatic cleaning apparatus 2000 may advance by a small distance in a direction in which this angle is directed; after advancing by a small distance, the automatic cleaning apparatus 2000 may turn back to the previous angle and continue to advance in the direction it turns back, and meanwhile detect the presence or absence of the carpet. If the carpet can still be detected, the automatic cleaning apparatus may further rotate by a certain angle and repeat the aforesaid process, and the mode of sweeping along the edge of the carpet as shown in FIG. 23 will be initiated until no carpet is detected.
- the automatic cleaning apparatus 2000 may change the direction after finishing the sweeping along the edge of the carpet, e.g., after finishing the sweeping along the edge of the first carpet 401 as shown in FIG. 24 . However, during the process of changing the direction, the automatic cleaning apparatus 2000 may detect another carpet, i.e., the second carpet 402 in FIG. 24 . If a gap between the first carpet 401 and the second carpet 402 is narrow, a carpet identifying device 103 fails to detect the second carpet 402 when the automatic cleaning apparatus 2000 enters the gap, because the carpet identifying device 103 is located at a side of the first carpet 401, the carpet identifying device 103 is not triggered at this time.
- the carpet identifying device 103 is triggered; and if the width of the gap is not large enough for the automatic cleaning apparatus 2000 to change the direction, the automatic cleaning apparatus 2000 may be trapped and cannot get out, thereby causing troubles to the user.
- the method may include the following steps S2610 to S2640.
- a boundary of a second surface medium region is scanned when the automatic cleaning apparatus cleans a first surface medium region, and a second surface medium region set is generated.
- boundary points in the second surface medium region set are treated as obstacle points and stored in a path searching map.
- passage paths to a target point are determined based on the path searching map if no obstacle-free path to the target point is searched out based on the obstacle points.
- the shortest path from the passage paths is determined, and the automatic cleaning apparatus is controlled to extricate itself along the shortest path.
- the automatic cleaning apparatus when the automatic cleaning apparatus is trapped by an obstacle as encountered when sweeping along an edge of the first surface medium region such as a wall, a carpet, and the like, the automatic cleaning apparatus may determine the obstacle points based on the boundary of the second surface medium region as scanned during the cleaning process; then, the automatic cleaning apparatus may determine the passage paths to the target point in conjunction with the obstacle points, and determine the shortest path from the determined passage paths, such that the automatic cleaning apparatus is then controlled to extricate itself along the shortest path, thereby helping the automatic cleaning apparatus to extricate itself as quickly as possible to avoid the trapping phenomenon.
- the method for controlling the automatic cleaning apparatus provides a method regarding how to enable the automatic cleaning apparatus to extricate itself after finishing the sweeping of a narrow gap region between a carpet and a wall or between two carpets, such that the trapping of the automatic cleaning apparatus can be prevented, the ability of the automatic cleaning apparatus to extricate itself automatically can be improved, and the failure rate of the automatic cleaning apparatus can be reduced, thereby improving the user experience.
- the method for controlling the automatic cleaning apparatus is applicable when the automatic cleaning apparatus is in a mode in which the carpet is not cleaned or a mode in which the wet cleaning module is initiated. Under the two modes, the automatic cleaning apparatus cannot move above the carpet, and is namely in a mode of only cleaning the first surface medium region. Thus, in the event that the automatic cleaning apparatus is trapped by a carpet, the method for controlling the automatic cleaning apparatus according to this example embodiment of the present disclosure can control the automatic cleaning apparatus to extricate itself as soon as possible with the shortest path, such that the probability of the automatic cleaning apparatus being trapped by the carpet can be reduced.
- first surface medium here is one or more of a ground surface medium such as wooden floor, carpet, tile, cement surface, and the like
- the second surface medium is one or more of a ground surface medium such as wooden floor, carpet, tile, cement surface, and the like, which is different from the first surface medium
- the automatic cleaning apparatus 2700 When the automatic cleaning apparatus 2700 sweeps a first surface medium region 2701 (e.g., the ground) along a wall and enters a location shown in FIG. 26 , the automatic cleaning apparatus 2700 may get trapped by a second surface medium region 2702 (e.g., the carpet) shown in FIG. 26 . At this point, the automatic cleaning apparatus may extricate itself by the method for controlling the automatic cleaning apparatus according to example embodiments of the present disclosure, which is specifically implemented as follows.
- a first surface medium region 2701 e.g., the ground
- a second surface medium region 2702 e.g., the carpet
- the boundary of the second surface medium region 2702 may be scanned during the cleaning process to generate a second surface medium region set, such that the automatic cleaning apparatus 2700 can extricate itself based on the second surface medium region set when trapped by the second surface medium region 2702.
- the boundary of the second surface medium region may be scanned with a second surface medium region identifying device, and the boundary of the carpet region may for example be scanned with a carpet identifying device 103.
- an initialized region 2800 as shown in FIG. 27 may be produced based on the boundary as scanned, and the initialized region 2800 is recorded in the automatic cleaning apparatus 2700.
- boundary coordinates of the initialized region may be merged. For example, adjacent boundary coordinates are merged into one coordinate to obtain a merged region 2900 as shown in FIG. 28 that is smoother than the boundary of the initialized region. As further shown in FIG. 29 , the merged region 2900 is split according to a predetermined shape to form a plurality of subregions 3001, 3002, and the plurality of subregions 3001, 3002 form the second surface medium region set.
- the predetermined shape may be square, round, and also other shapes such as rhombus.
- the subregion 3001 is a square region and the subregion 3002 is a round region as determined according to the predetermined shape.
- Example embodiments of the present disclosure do not particularly define the specific predetermined shapes.
- the boundary points in the second surface medium region set may be treated as obstacle points and stored in the path searching map.
- the boundary points in each subregion 3001, 3002 of the second surface medium region set are all used as obstacle points, and the obstacle points are added to the path searching map.
- the automatic cleaning apparatus when searching for a path based on the path searching map, may avoid the obstacle points and instead look for an obstacle-free path to avoid the occurrence of trapping.
- a passage path to the target point 2703 may be determined based on the path searching map.
- the method for controlling the automatic cleaning apparatus can typically determine a plurality of passage paths, and then determine the shortest path from the plurality of passage paths, such that the automatic cleaning apparatus 2700 can be controlled to extricate itself along the shortest path.
- the method for determining the plurality of passage paths includes following methods.
- the first passage path determining method firstly includes performing a step of deleting target obstacle points.
- the step of deleting the target obstacle points includes determining, based on the path searching map storing obstacle points therein, a reachable region 3101 and an unreachable region 3102 of the automatic cleaning apparatus 2700 based on a current location of the automatic cleaning apparatus 2700.
- the reachable region 3101 refers to a region to which the automatic cleaning apparatus 2700 can move without touching the obstacle points
- the unreachable region 3102 refers to a region to which the automatic cleaning apparatus 2700 cannot move without touching the obstacle points.
- the obstacle points on a connection boundary 3103 between the reachable region 3101 and the unreachable region 3102 can be found according to the connection boundary 3103, to be treated as the target obstacle points 3104, and the target obstacle points 3104 are then deleted from the path searching map.
- the boundary of the reachable region 3101 may be expanded, thereby changing the connection boundary 3103.
- the step of deleting the target obstacle points on the new connection boundary is performed to delete the next target obstacle point 3105 to further expand the boundary of the reachable region 3101.
- the step of deleting the target obstacle points is repeated until the passage path 3106 to the target point 2703 is found from the path searching map where the target obstacle points have been deleted.
- the obstacle points on the connection boundary close to the automatic cleaning apparatus may be found as the target obstacle points, by deleting the target obstacle points, the possibility that the passage path as acquired is the shortest path is increased.
- the first passage path determining method it is possible to acquire a plurality of passage paths, and the shortest path may be determined from the plurality of passage paths to facilitate the passing and extrication of the automatic cleaning apparatus.
- a region having the smallest area i.e., subregion 3002 is determined from the second surface medium region set. Then, the boundary points of the region 3002 having the smallest area are deleted from the path searching map. Since the obstacle points are composed of the boundary points including the subregion 3002, deleting the boundary points of the subregion 3002 is equivalent to deleting the obstacle points corresponding to the subregion 3002. Afterwards, the obstacle points in the path searching map are updated. Then, the passage path 3201 to the target point can be determined from the updated obstacle points.
- the passage path 3201 may be directly determined as the shortest path to control the automatic cleaning apparatus 2700 to pass along the path. It is also possible to determine the shortest path in combination with the passage path determined by the first passage path determining method, which is not specifically limited by example embodiments of the present disclosure.
- a plurality of passage paths can be determined simultaneously according to the first passage path determining method and the second passage path determining method, and the shortest path is then selected from the plurality of passage paths as an optimal path, to facilitate the automatic cleaning apparatus to extricate itself along the shortest path.
- the boundary points of the second surface medium region as scanned may be treated as the obstacle points.
- the obstacle points may be deleted by different methods such as the first passage path determining method and the second passage path determining method, to determine the shortest path for the automatic cleaning apparatus, such that the path of the automatic cleaning apparatus passing over the second surface medium region can be reduced, and namely the crushing of the automatic cleaning apparatus on the second surface medium region can be minimized, thereby facilitating the automatic cleaning apparatus to extricate itself as soon as possible.
